Hey I've got a non-head-fier friend interested in this.  What kind of impedance headphones can you run with the 5x gain?  250ohm Beyers?


Also, hows the imagery/separation and soundstage increase that you've noticed?  I've never had a chance to hear a Mini3.

CARRIE amp does not use an adapter or batteries.

Power source only comes from USB (5V for GrubDAC) and using a DC to DC step up (5V to 15V), regulated to 12V and is set to be divided by the TLE2426 to + / - 6V (for Mini3 amp).


So the CARRIE amp is very convenient to carry around. You only need a USB cable.
